Why LPG Is the Cleanest Cooking Option for Nigerian Homes

Walk into any Nigerian kitchen and you’re likely to find a gas cylinder in the corner. But the type of fuel it contains — and how clean that fuel actually burns — varies enormously. LPG (liquefied petroleum gas) is the cleanest option widely available for household cooking in Nigeria. Understanding why matters, both for your health and for the environment your household contributes to.

What actually comes out of your stove?

Every cooking fuel produces a combination of heat, carbon dioxide (CO²), carbon monoxide (CO), and fine particulate matter (PM2.5). The ratio depends on the fuel type and how completely it burns.

Solid fuels like wood, charcoal, and crop residues burn incompletely at typical cooking temperatures. This incomplete combustion produces large quantities of PM2.5 — particles so small they bypass your nose’s filtering system and lodge directly in lung tissue. Long-term exposure causes chronic obstructive pulmonary disease (COPD), lung cancer, stroke, and cardiovascular disease.

LPG burns with a blue, near-complete flame. Combustion efficiency typically exceeds 90%, which means less carbon monoxide and dramatically fewer fine particles entering your kitchen air.

Switching from firewood or charcoal to LPG reduces indoor fine particle concentrations by approximately 90%. Over a lifetime of cooking, this is the difference between healthy lungs and chronic respiratory disease.

The CO² numbers

If you care about your household’s carbon footprint, the fuel comparison is unambiguous:

• Firewood: approximately 1.9 kg CO² equivalent per kilogram burned (plus significant deforestation impact)
• Charcoal: approximately 3.6 kg CO² equivalent per kilogram burned (the charcoal production process is highly inefficient)
• Kerosene: approximately 2.5 kg CO² equivalent per litre
• LPG: approximately 1.5 kg CO² equivalent per kilogram — and it burns with higher energy efficiency, so you need less of it per meal

Charcoal is particularly misleading because people assume “it’s wood, so it’s natural.” The production process converts approximately 10 kg of wood into 1–3 kg of charcoal, wasting 70–90% of the wood’s energy and producing significant emissions in the process. When you burn charcoal, you are effectively burning all of that wasted wood twice.

What this means for Nigeria specifically

Nigeria loses approximately 350,000–400,000 hectares of forest per year — one of the highest deforestation rates in the world. A significant driver is firewood and charcoal production for household cooking. Every household that switches from solid fuels to LPG directly reduces demand for biomass fuel and the deforestation that comes with it.

The health toll is equally serious. The WHO estimates over 3 million Africans die annually from diseases linked to indoor air pollution from solid cooking fuels. The vast majority of these deaths are women and children, who spend the most time near cooking fires.

The cost comparison

A common objection to LPG is cost. At first glance, firewood or charcoal appears cheaper per purchase. But this ignores two things: thermal efficiency (how much of the fuel’s energy actually reaches your pot) and the health costs that accumulate over years of exposure to solid fuel smoke.

LPG’s thermal efficiency of 55–65% significantly outperforms charcoal (20–25%) and firewood (15–20%). On a per-meal basis, properly adjusted for how much fuel you actually use to cook a pot of rice, LPG is often cheaper than the alternatives.

What the SDGs say

Three UN Sustainable Development Goals directly address the transition away from solid cooking fuels. SDG 7 (Affordable and Clean Energy) includes a specific target for universal access to clean cooking fuels. SDG 3 (Good Health and Well-Being) targets reducing deaths from air pollution. SDG 13 (Climate Action) calls for measurable reductions in household emissions.

The transition to LPG is one of the highest-impact, lowest-cost interventions available for households in developing economies. It does not require new infrastructure or government programmes — it requires a reliable, trustworthy supplier with verifiable weights and fair prices.
